Sounds good.

I'm guessing that that means you send a piece of E-mail, which gets
routed to a fax server on your mail host, and that message ends up not
being routed to the fax server because your sendmail is deferring all
E-mail (even mail to local users and programs).
Have you tried separating your E-mail traffic into local-net and
external-net traffic? Sendmail can be told that local-net traffic is
"cheap", and that external-net traffic is "expensive", and then it can
be further configured to defer expensive traffic until later, while
allowing inexpensive traffic to flow freely.
Of course, configuring all this is beyond the scope of IP Masq, and is
also not terribly easy, as far as I remember. I like to hack sendmail
as much as the next guy, but getting it right will be a troublesome
process. However, I'm just letting you know that it's possible, if you
want to persue that angle.

Sure, that could work. In fact, it makes sense to separate the firewall
and other services, from a security standpoint. It makes your firewall
more difficult to penetrate if it is not running any exploitable services.

Sure. Sendmail can do anything. It's all a matter of configuration. :)
